cytoreductive surgery
Surgical removal of as much tumor tissue as possible to reduce tumor burden and enhance effectiveness of adjuvant therapies.
Full Definition
Cytoreductive surgery in neurosurgical oncology refers to the surgical approach of removing the maximum amount of tumor tissue safely achievable, even when complete resection is not possible. This strategy aims to reduce overall tumor burden, potentially improving patient outcomes and enhancing the effectiveness of subsequent radiation therapy or chemotherapy. The procedure is particularly relevant in cases where tumors are located in or near critical brain structures that preclude gross total resection. Success is measured by the percentage of tumor removed and the preservation of neurological function.
Usage
Usage note: Often confused with gross total resection; cytoreductive implies incomplete but maximal safe removal.
